D-backs Prospect Hagaman Shines in Season Opener

David Hagaman, a highly-touted prospect for the Arizona Diamondbacks, finally made his 2026 season debut with the High-A Hillsboro Hops on Wednesday. The 23-year-old right-hander, considered the eighth-best prospect in the D-backs system and second-best pitcher, delivered an impressive performance over two innings. He allowed no hits or runs, issuing two walks while striking out an outstanding five batters.

Hagaman's season debut was delayed, with the pitcher participating in extended spring training since April 9 to build up his arm. He was not given a traditional injury designation, suggesting possible general fatigue or soreness managed internally. Hagaman was a key return piece in the 2025 trade that sent Merrill Kelly to the Rangers, alongside twin left-handers Mitch Bratt and Kohl Drake.

Despite being the furthest from the majors among the three prospects from that trade, Hagaman possesses a high ceiling. He posted a 3.15 ERA with 27 strikeouts in 20 High-A innings after the trade last season. His full 2025 season stats included a 2.98 ERA and 55 strikeouts in 42.1 innings across three levels. A promotion to Double-A Amarillo could be on the horizon once he is fully ramped up.
